The Outdoor Research Dry Isolation Pack is a waterproof pack for pushing to the summit. When the weather isn't up to scratch, you can still make the push when your essentials are stored in this 18L pack. At just 4.1 ounces, it is ultralight AND prevents the gear inside from getting soaked. Whether you're packing your keys and ID to an extra layer, snacks and a camera. Once you've made it back to camp, it packs down into an included stuff sack, fitting in the palm of your hand.
So sorry, but only 4 items are allowed for comparison, so we're comparing the first 4. I blame the gnomes and so should you.
